Fargate with Docker compose Links

We have an application that uses docker compose that contains links.

I'm trying to deploy this using aws-cli on Amazon Fargate using this command:

ecs-cli compose --project-name myApp --file docker-compose-aws.yml --ecs-params fargate-ecs-params.yml --cluster myCluster --region us-east-1 up --launch-type FARGATE

When my fargate-ecs-params.yml has ecs_network_mode: awsvpc I get the error: Links are not supported when networkMode=awsvpc

So I've tried changing to ecs_network_mode: awsvpc, however I then get the error: Fargate only supports network mode ‘awsvpc’

My question is how do I create a task definition for Fargate with a compose file that contains links? Or is this not possible (and in that case then what are my alternatives?)

After reading your final comment on the boot sequence and answering that question instead, I solved this (even in non-AWS) using the docker-compose depends.

Simple e.g.

services:
  web:
    depends_on:
      - "web_db"
  web_db:
    image: mongo:3.6
    container_name: my_mongodb

You should be able to remove the deprecated links and just use the hostnames that docker creates from the service container names. e.g. above the website would connect to the hostname: "my_mongodb".
